     This test verifies that we reconstruct frames as necessary, after content
     (including whitespace & spans) is dynamically inserted as a child of a
     flexbox.  (Note that in cases where we know the whitespace is going to be
     dropped, we don't bother reconstructing frames. This test is to be sure we
     aren't overzealous with that optimization.)
